Description
Technical Field
The invention relates to the field of storage batteries, in particular to a lead-acid storage battery repairing agent and a preparation and use method thereof.
Background
A lead-acid battery (VRLA) is a battery whose electrodes are made mainly of lead and its oxides and whose electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in a charged state, the main components of the positive electrode and the negative electrode are lead sulfate. The nominal voltage of a single-lattice lead-acid battery is 2.0V, and the battery can be discharged to 1.5V and charged to 2.4V; in application, 6 single-cell lead-acid batteries are often connected in series to form a lead-acid battery with a nominal 12V, 24V, 36V, 48V and the like.
The service life of the lead-acid storage battery is greatly influenced by the discharge depth, the design consideration is mainly on deep cycle use, shallow cycle use or floating charge use, and if the battery used in the shallow cycle is used in the deep cycle use, the lead-acid storage battery can be rapidly failed. Lead sulfate is generated during discharge and recovered to lead dioxide during charge because the positive electrode active material lead dioxide itself is not firmly bonded to each other, and the active material expands in volume during discharge when the molar volume of lead sulfate is larger than that of lead oxide. If one mole of lead oxide is converted to one mole of lead sulfate, the volume increases by 95%. Thus, the mutual combination between the lead dioxide particles is gradually loosened and the lead dioxide particles are easy to fall off after repeated contraction and expansion. If only 20% of the active material of one mole of lead dioxide is discharged, the degree of contraction and expansion is greatly reduced, and the binding force is slowly damaged. Thus, the deeper the depth of discharge, the shorter its cycle life.
The method for prolonging the service life of the lead-acid storage battery is generally repair by adding water, but the service life of the storage battery is extremely limited by the repair method, and the performance improvement in various aspects such as discharge time is not obvious.

If the discharge time is too low, the capacity is too small, the probability of damage of the polar plate is very high, and the polar plate is removed.
2.

3. The glass fiber separator in the storage battery is fully wetted by visual inspection, and if the storage battery is dry, special stock solution (electrolyte) for the storage battery is required to be added, deep discharge is continued to 0V, memory is removed by deep discharge, so that the plate can be softened and then vulcanized, crystallized and dropped, and the sulfur removal effect is enhanced.
